Nexperia USA Inc. PZU884LS-C2V7-QYL

Overview

PZU884LS-C2V7-Q from Nexperia is a surface-mount Zener voltage regulator diode in the PZU884LS-Q series, designed for precision voltage reference and regulation in space-constrained automotive and industrial circuits. It delivers a nominal 2.7 V Zener voltage with ±5 % tolerance, 1000 Ω differential resistance at 5 mA, and 440 pF capacitance at 1 MHz, operating up to 150 °C junction temperature.

For engineers reviewing the PZU884LS-C2V7-Q datasheet, PZU884LS-C2V7-Q pinout, PZU884LS-C2V7-Q application, or PZU884LS-C2V7-Q equivalent, this device is evaluated for low-leakage, hard-knee breakdown performance in power rail stabilization, ESD-protected sensor biasing, and automotive microcontroller reference circuits where side-wettable flanks support automated optical inspection (AOI) and solder joint reliability.

Technical Context

This Zener diode belongs to the "C" tolerance subgroup of the PZU884LS-Q series, optimized for general regulation with very low leakage current and a sharp breakdown knee-distinct from the "B" series which trades higher leakage for faster switching and noise reduction per AN90031. Its operation relies on controlled avalanche breakdown in silicon, with thermal coefficient of −3.5 mV/K at 25 °C and 5 mA test current.

The device uses a planar epitaxial construction with side-wettable flanks (SWF) in the DFN1006BD-2 (SOD882BD) package, enabling reliable reflow soldering and AOI compatibility. Its 0.65 mm pitch, 1.0 mm × 0.6 mm footprint, and 0.47 mm height are specified per IEC JEDEC MO-343AA, with cathode identified by a marking bar on the top surface.

FAQ

What is the maximum reverse voltage this Zener can regulate continuously?

The PZU884LS-C2V7-Q is rated for continuous Zener operation at its nominal 2.7 V working voltage, with absolute maximum reverse voltage limited by its 365 mW total power dissipation at 25 °C ambient. At 2.7 V, this corresponds to a maximum continuous Zener current of approximately 135 mA-assuming no additional thermal derating. Actual usable current must be reduced per R_th(j-a) = 340 K/W to maintain T_j ≤ 150 °C in real PCB layouts.

Does this part support automated optical inspection (AOI) during SMT assembly?

Yes-its DFN1006BD-2 package features side-wettable flanks (SWF), allowing AOI systems to inspect solder joint formation on the lateral edges of terminals 1 and 2. This design meets IPC-A-610 Class 3 requirements and is validated for use in high-yield automotive electronics manufacturing lines where solder joint reliability is mission-critical.

How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

With a specified temperature coefficient of −3.5 mV/K at 25 °C and 5 mA, the PZU884LS-C2V7-Q exhibits predictable negative drift: V_Z decreases ~0.35 V across a 100 K range. For example, at 125 °C, V_Z shifts to ~2.35 V (−0.35 V), remaining within its ±5 % initial tolerance band (2.50–2.90 V). This behavior is documented in Figure 3 of the datasheet and supports stable biasing in wide-temperature applications.

Can this Zener replace older through-hole Zeners like 1N4732A in new designs?

No-it is not a drop-in replacement due to fundamental differences: PZU884LS-C2V7-Q is a surface-mount, 2-terminal, 2.7 V ±5 % Zener in a 1.0 mm × 0.6 mm DFN package, whereas 1N4732A is a through-hole, 4.7 V ±5 % device in DO-41. Direct substitution would require PCB redesign, voltage-level reassessment, and verification of thermal performance in the new footprint. Use only when the full system-level impact of voltage, package, and thermal characteristics is revalidated.
